Carbon fiber and glass fiber (fiberglass) are similar in some ways, but there are also many significant differences.
Similarities
1. Composites: Both are commonly used as reinforcing materials in composites, often in combination with resins to increase the strength and rigidity of the material.
2. Lightweight: Both carbon fiber and fiberglass are lighter than many traditional materials, such as metal and wood, making them popular in a variety of applications.
3. Corrosion resistance: Both materials have good corrosion resistance and are not easily affected by chemicals.
4. High strength: Both are stronger than many conventional materials, but carbon fiber is usually stronger.
What is the density of carbon fiber board?
The density range of carbon fiber board is around 1.5~1.8g/cm3. Carbon fiber boards are made from carbon fiber composites, where the density of the carbon fiber itself is around 1.75g/cm3, the density of commonly used epoxy resin is 1.4g/cm3, and the density of phenolic resin is 1.10g/cm3.
Although the density of carbon fiber board is very low, but can improve the tensile strength is very high. Carbon fiber tensile strength can be more than 3000MPa, and carbon fiber plate tensile strength can also reach 1500MPa, while the tensile strength of ordinary steel is 600MPa, so in this aspect of strength, carbon fiber materials occupy a greater advantage. Combined with the 2 advantages of light weight and high strength, carbon fiber board has been used more in industry.
What is the density of glass fiber board?
The density of fiberglass board is around 2.2~2.5g/cm3, which is higher than that of carbon fiber and lower than that of aluminum metal (2.7g/cm3). Fiberglass boards are made of fiberglass composites, in which the density of glass fibers itself is in the range of 2.4~2.76g/cm3, and the density decreases after combining with resin.
Glass fiber board in the density is slightly higher than carbon fiber board, the gap is not very obvious, but the tensile strength of glass fiber between 1000 ~ 2000MPa, glass fiber board tensile strength will be a little lower, a comprehensive look at the performance of glass fiber board in the mechanical properties is significantly worse than the carbon fiber board, which is the fundamental reason why many companies will use carbon fiber board instead of fiberglass board.
Carbon fiber board, although lighter than glass fiber board, but can not completely replace the glass fiber boardSee here, you may think that the carbon fiber board sooner or later will one day be able to completely replace the glass fiber board, this point of view in the future may be possible to achieve, but in the present can not be reached.
The production process of glass fiber board is simpler, the manufacturers of equipment and personnel requirements are relatively low, and can be more high-volume output of glass fiber composite materials, low technical threshold, so that the total amount of glass fiber board is guaranteed, in the absence of the pursuit of the ultimate performance, more companies will choose glass fiber board.
In addition the price of carbon fiber board is a few times or even a dozen times the price of glass fiber board, a huge price gap so that many companies are not willing to improve production costs, which is the fundamental reason why the current glass fiber board is still in a large number of applications. If there is a breakthrough in the future process technology of carbon fiber board, and production capacity has a huge increase, it is possible to achieve carbon fiber board completely replace the results of glass fiber board.
